Body powered first aid nanobot technology…
What we actually have here is an amazing step forwards in medical science. Using the power stored within the body itself, it is now possible to run tiny implants that otherwise would have needed limited lifetime batteries to run.

Just imagine a future where first aid can be provided right at the point of injury, by utilising nanobots that harness their energy from the very blood stream they inhabit.
Or self diagnostic computer systems, that sit within the body quietly monitoring systems such as blood pressure, sugar levels, infection symptoms and the like. This information could then be downloaded remotely for analysis, or alert automatically when first aid is needed.
Very tomorrows world!
